What is a solution of an equation in one variable?
A solution to an equation is a value that makes the equation true. In a one-variable equation, the solution is the value that makes the equal sign true. For example, in the equation 2x + 5 = 18, the solution is x = 5. To solve an equation, you isolate the variable by subtracting both sides of the equation by the constant term. Then, divide both sides of the equation by the coefficient of the variable. You will then have to solve the equation by using one of the algebraic methods such as factoring or using the quadratic formula.
